Hi HN, I'm the co-founder/CEO of Causal. We just announced our acquisition: https://www.causal.app/blog/causal-joins-the-lucanet-group
Just wanted to say a big thank you to the HN community —
Everything started with this post from over 5 years ago [1] which gave me and Lukas (CTO) enough conviction to quit our jobs to work on Causal full-time.
A few months later we launched an Excel sensitivity tool [2]. In 2022 we shared how we scaled our calculation engine to billions of cells [3] and a few months ago we had a successful Show HN of Causal 2.0 [4]
The product is now used by 100s of startups (many YC companies) and we're excited for this next phase of growth within Lucanet :)

I was building something similar back during COVID, as LTSE's Runway stopped being improve, Summit (usesummit.com) pivoted to being a no-code tool and Obvious (YC S21 perhaps?) shut down.
Instead of building it myself, I found and have been using Causal actively since April 2021 and advocating for it ever since, using it heavily for my latest three ventures and just last month for personal use. It's so far one of my favorite products to use, on level with Linear in terms of quality!
I'm not a commercial user and might never be, but it has been invaluable for me in my commercial and personal uses for budgeting and forecasting.
Hope you can fit in great at Lucanet, and try your best to keep the free model available!
Nothing will change for existing users so you can keep using it for sure :)
A related question, if you don't mind me asking: was acquisition your initial goal when you founded Causal, or did you just receive an offer you couldn't refuse?
We didn’t have an end goal in mind from the beginning — we had the idea for the product and wanted to see if it had legs as a business, and then grow it and see where we could take it.
From what I recall, I don’t think this kind of acquisition was on our radar in the early days — we expected the startup game to be much more binary (massive outcome or bust), and this was the standard narrative at the time.
We’re fortunate to have landed in a middle ground that more founders should be aware of earlier on (and I think awareness is increasing).
Not a massive outcome by VC standards, but still a win for us, our team, our customers, our product, and our early investors, and not the end of the journey yet!
You mean the area 97% of businesses who don't go bust operate? I think most business owners are well aware of it. For some reason though, startup founders live in a different reality.
I haven’t checked out Tanstack table much but given that it’s such a core component of the product I would like to build our own eventually. Doing that when you start out is probably not worth it though.
I would recommend AG-Grid for most data apps until a well supported alternative comes out. My understanding is that Tanstack Table is aimed at generic apps that happen to have a table. Perspective's [2] table component is most likely more capable than AG-Grids, but it needs significantly more documentation and examples.
AG-Grid has a particular way of building things that seems to map to well to pulling data from a database or basic webservice. AG-Grid works very well for this use case. The AG-Grid enterprise features are built around this type of data model too.
If your data is small enough to fit into memory (less than 50 MB), it works very well. AG-Grid doesn't have a connector to arrow or parquet (I will eventually write my own). For larger datasets JSON generation and parsing performance bottlenecks. Additionally Parquet/Arrow offers much better types.
Configuring AG-Grid is tricky, especially when you want config to be declarative. If you want to define your own custom rendering components, getting them to work properly per column when you want different renderers for pinned rows is tricky (my solution [3])
Support for the community version of AG-Grid is practically non-existent. I understand that they have an enterprise business model that charges for support. They don't seem to be interested in answering community bug reports or comments, even for generically relevant bugs.
I have a decent amount of trust in AG-Grid's community offering [4], I don't see them cannibalizing community features to put them in their enterprise offering. Their enterprise features are the main development focus of the team, particularly the charts. The charts offering isn't impressive compared to bokeh, plotly, or vega. It would work for line of business apps, but not for a userbase familiar with better analytic platforms.
All that said. AG-Grid has excellent documentation and examples. They examples are swappable between Javascript, Typescript, React, and Angular.

Would Perspective work for a similar use case as Causal's where the data tables have a large amount of interactivity, tree-based information and/or master-detail style UI concerns?
We're building a product that is more oriented around the interactive DAG concept and less about big data. The snappiness of those examples is very impressive.

Do you think the US flip made a meaningful difference (presuming you did it for US customer/investor access)? Lucanet is EU, so maybe it complicated it in the end
